ROBERT PUTNAM NORTON, OF ST. THOMAS, NORTH DAKOTA.

CARCOUPLING.

SPECIFICATION forming part of Letters Patent No. 655,886, dated August 14, 19001.

Application tiled April 23, 1900. Serial No. 14,010. (No model.)

T0 a/ZZ whom it may concern:

Beit known that I, ROBERT PUTNAM NoR- TON, a citizen of the United States, residing at St. Thomas, in the county of Pembina and State of North Dakota, have invented certain new and useful Improvements in Car-Couplers; and I do declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in car-couplers of the pin-and-link type, and has for its primary object the provision of means whereby the pin may be elevated or lowered either from the sides or top of a car.

An embodiment of the invention for the purposes of illustration is shown-in the accompanying drawings, and in hereinafter referring to the same like letters of reference designate corresponding parts in the several views.

Figure l is an end view of a car with my improvement attached thereto. Fig. 2 is a side view of the same. Fig. 3 isa detail view of what I will term the operating-wheel and its associated parts, and Fig. 4t is a detail view of one of the operating-rods.

Referring more specifically to the drawings, A represents a portion of the ordinary car-body, and B the draw-head, secured on the under side of the same. The draw-head in the main is of the usual configuration and has a centrally-arranged aperture in which a vertically-movable pin O is adapted to work to secure and release the link. (Shown in dotted lines.) Mounted in a central position slightly in rear of the opening in the drawhead in bearings din flanges d on the drawhead is what I will hereinafter term an operating-wheel D. This wheel is designed to be turned by mechanism hereinafter described either from the outside of the car or from the top thereof to elevate and lower the coupling-pin. The periphery of the operatingwheel extends forward to a position in substantially the vertical plane of the opening in the draw-head and carries at its lower forward edge Vngers or catches E, designed to engage notches e, formed in the upper portion of the draw-head, and thereby limit the turning movement of the wheel when operated in the direction of the arrow, Fig. 2. These fingers or catches are in turn guided in apertures formed in a tiange E', projecting upwardly from the draw-head. At a desired position on the end of the car I mount in suitable bearings the operating-rod F, provided with the usual cranks F at its respective ends and having the loop portion F2 projecting forwardl y around the wheel D and secured thereto at f. A link G is connected to the extreme end of this loop and pivotally connects the same with the coupling-pin. It will thus be seen that whenever the cranks F are turned the wheelwill be correspondingly rotated and the pin elevated or lowered, as the case may be, the fingers E limiting the upward movement of the same, as hereinbefore described. Also pivotally secured at the point f to the operatiugwheel and extending upwardly therefrom is a link G, in turn pivoted to another link G, which latter is attached to the offset portion h of the vertically-movable operating-rod H, carried by the car. The movement of the rod H upward or downward will effect a turning movement of the operatingwheel and a corresponding raising or lowering of the coupling-pin From the above description it will be seen that I have provided a simple construction whereby the coupling-pin may be raised or lowered either from the sides or the top of a car through the medium of a single operatin g-wheel and its requisite associate parts.

Having thus described my invention, what Iclaim as new, and desire to secure by Letters Patent, isp In a car-coupler, the combination with a draw-head, of a pin operating therein, and means for raising and lowering said pin comprising an operating-wheel, connections between the pin and said wheel, means for rotating said wheel, and means for limiting the rotary movement of said wheel, comprising catch-fingers carried by the wheel adapted to engage the draw-head, substantially as described.

In testimony Whereof I afix my signature in presence of two witnesses. l

ROBERT PUTNAM NORTON.
